MODE(VARIANTS) AND AN ARRANGEMENT(VARIANTS) OF ELECTRIC SUPPLY OF PREDOMINANTLY PORTABLE ELECTRON AIDS

摘要

FIELD: the invention refers to the sources of electric supply of electron aids whose functioning is carried out on the principles of electronic engineering and/or radio technique.;SUBSTANCE: the aids include at least one active element with three or more electrodes particularly a transistor and using this active element(elements) carry out amplification, conversion or generation (formation) of working electric signals of alternating or direct voltage including broadband signals. The mode and the arrangement for electric supply of predominantly portable electron aids is carried out by way of using at least one a three-electrode active element, amplification, conversion or generation of an electric signal of alternating or direct voltage based on supplying voltage on the clamps of the electron aid, impulse voltage whose on-off time ratio is within the limits of 1,1-20,0 is used as supply voltage. In the second variant of the mode and of the arrangement the impulse voltage has the following parameters: the frequency of impulses is at least one level higher than the maximum frequency of the spectrum of the electric signal of alternating voltage or at least one level less than the minimal frequency of the spectrum of this electric signal, and the duration of the impulse fronts is at least one level less than the magnitude inverse to the maximum frequency of the spectrum of the electric signal of alternative voltage.;EFFECT: decreases electric consumption.;10 cl, 3 dwg
